I'm a Director-level in Engineering at a startup. I get at least 20 cold emails per day trying to sell me on some software or another. I ignore all of them and never respond.

I get a lot of recruiters emailing, too. If they're trying to get me to hire ICs, I typically ignore them. If they have candidates that are around my level, I may respond to add them to my network in case I decide to look for a job again and need to find some non-obvious opportunities.

But as far as getting me to hire someone, it's wildly ineffective, IMO.
